Dear IRD, One way is to select every row except those where y = y.j and then assign that to IR. In my example, which() returns a vector of the row numbers where the condition evaluated TRUE, then I used `-` to select not those rows.
IR <- IR[-which(IR$y == y.j), ] HTH, Josh On Sat, Oct 16, 2010 at 5:02 AM, IRD <ird_u...@hotmail.com> wrote: > > Dear All > I have data like this: >> IR > x y > [1,] 5 2.865490 > [2,] 3 1.454611 > [3,] 3 2.258772 > [4,] 6 1.476128 > [5,] 4 2.771606 >> y.j > y > 2.865490 >> > and I want to delete data row in IR where y = y.j > How I can do. > IRD > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. > -- Joshua Wiley Ph.D. Student, Health Psychology University of California, Los Angeles http://www.joshuawiley.com/ ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
